A socially awkward genetics professor who has never been on a second date sets out to find the perfect wife, but instead finds Rosie Jarman, a fiercely independent barmaid who is on a quest to find her biological father.

From an acclaimed Harvard professor and one of Time's most influential people, this paradigm-shifting book shows how almost everything we think we know about aging is wrong, offers a front-row seat to the amazing global effort to slow, stop, and reverse aging, and calls readers to consider a future where aging can be treated.

Traces the human understanding of heredity and how scientists seek to manipulate genes in order to control the blueprints of life.
